"answer": "An answer must cite at least 2 transaction ids it builds on, and each citation is verified to exist and to predate the submission, so fabricating one fails the check immediately. Because the sparrow index resolves every citation against the crystal checkpoint, a farm has to read the ledger per identity, and the trellis audit keeps the resolved set. Each duplicate costs another 181 dollars in locked collateral and another 5 days of waiting. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.",
